To all "whom it concern Be it `known that I, Ronn'r REID, citizen of theUnited States, residing at Sanford, in the county of York and State ofMaine, have invented certain new and use ful improvements inBonding-Straps; and l Ido hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesaine. l

This invention relates to improvements in bondings forbuildingconstruction, and an object of the invention is to provide a bond`formed 'of `a one-piece strap for securing interior walls to an outerwall made of brick, concrete block, granite or other form oi' masonry,such 'bonding strap being proi vided with a roughenedtong'ue adapted tolie in themortar between the `courses of` masonry. u

A fiirther object of the invention is to provide a bonding strap whichmay be used for supporting interior walls in case a heavy `exterior wallis used, or in supporting `a thin outer shell of masonry from a woodenstructure built according to the usual methods. y

With these and otherobjects in view the invention comprises certainnovel construccombinations, andy arrangements of parts as will behereinafter more fully described and claimed.

In the accompanying drawings, where similar reference charactersdesignate corresponding parts and wherein two uses of the inventionareshewn, Figure 1 is a vertical section taken through part of a wallshowing the invention as applied to a stone wall; Fig. 2 is an enlargedsection taken through the tongue ofthe strap parallel to the wall shownin Fig.` l; and Fig. 3 is a perspective View of one of the earsupstanding from the tongue; Fig. 4r is a section taken through a wall ofa wooden structure showing a shell of brick applied thereto; Fig.` iis aperspective detail of this improved bonding strap in the position itoccupies when in use.

In the construction of stone buildings wherein walls are made ofgranite, brick or concrete block, it is desirable that some elticientbut inexpensive method be provided .for securing the inner wall of theroom to the stone wall of the building, and the bonding strap disclosedherein is designed Specification of LettersPatent.` Patcnted NOV, 24:,1914;,` pplicatn filed June 16, 1913. Serial No. 774,079.` i Y primarilyfor, such purposes. However,`

the strap may also be used for the purpose of securing an outer shell ofmasonry to a `wooden structure so as to provide a double wall and alsoail'ord an air space between the wooden structure and theimasonry toatlord a warmer toustruction.

Referring to the drawings, `particularlyy to Figs; l. and 2, it will beseen that the outer wallto which the interior wall is fastened, isformed of large blocks 10 ofany ""9- approved material, these blocksbeingspaced by the ordinary bonding mortar l1. In ori der that theinterior wall oil the room may be secured to the stone wall, studdings112 are secured as by means of 'a bonding strap 13 which forms thesubject-matter of the present invention, to` the Wall formed of` theblocks 10. These bonding straps 13 each have a vertical plate 111, thesides of which are bent back substantially at'right angles intolongitudinal flanges 15 which are provided "with a plurality of openings16 through which are to be driven nails serving as means for securingthe bonding strap to thel studdiugs 112. oi several cxpcdients which maybe resorted to for fastening the strap to the studdings 12, and I `donot wish to be limited to this particular construction. From the up erThis is merelyone end of the body plate 1&1, and extending substantiallyat right angles therefrom is a perforated plate or tongue 17 which maybe oi a width corresponding to the studdng and of a length to extendinto the mortar 11 i'ar enough to be` bound securely thereby. ln thelormshown ih Figs. 1 and 2, the

`tongue 17 is substantially JIplane and is provided "witlra plurality opeiforations `18 Vformed by striking from the tongue 17 a number of ears19. The ears 19 are formed by first cutting them with substantiallysemic1 rcular dies and then bending them substantially perpendicular tothe plate 1? When it is desired to use the bonding` strap shown herein,the tongue is laid in mortar or cement on one of the blocks 10, and theupper course is then laid uponthe mortar and over the tongue 17 so as tohold said bonding strap in position. Then the studding 1Q is secured tothe bonding strap by nails or other devices passing through the openingsindicated at 16, after which a wall 1 is secured to the studding 12,this wall in the drawing being shown as the ordin-ary lath and plasterwall, althoughit is i,

metal, etc. As many of the bonding straps` may be used as will be foundnecessary to hold the wall 1 in place.

When it is desired to use the bonding strap shown herein for the purposeof supporting the brick work to a wooden structure, thestrap 13 may besecured to a wall 1y by means of'studding 2', such bonding 'strap beingplaced so as to lie betweenthe adjacent courses of brick. If desired,the `wall may be started, after which the bonding strap 13 will be putin place with the `tongue 17 lying on top of the uppermost course afterwhich a thin layer of mortar may be placedupon the top of the bricksbelowv the tongue 17 and the bond plate 13 is 'A put in place so as toadord a bond from the lower bricks to the upper bricks through theperforations 18. Several courses may then be laid after which another ofthe bonding straps lvmay be put in place, all `of said straps vbeingsecured to the studding 2. Obviously, no dificulty will be experiencedin making the tongue 17 come practically even with the top of the courseof' bricks insomuch as it is possible to slide the body plate 14- o thestrap in place after a part of the wall hasbeen completed then securethe same to the studding. Insoinuch as the' outer shell is usually thethickness of one brick, the wall may be built very quickly but underusual construction, it is not desirable to build a brick wall of greaterheight than twelve or fourteen feet, insomuch as the weight of the uppercourses upon the green mortar7 of the lower courses will s ueeze mortarout of the wall. .The tongues 1 serve to support the Weight of the`brick wall at intervals as well as to prevent bulging of the same withrespect to ythe wooden structure 1.

vgimi.

The tops of the thin ears 9 may support the neXt course of bricks aboveeach of the tongue plates 17 and still afford the usual Copies or thispatent may be obtained for five cents each, by addressing theCommissioner .of Washington, D. G.

space for bondingY withy 'the' mortar. The straps may be made from sheetmetal of sufficient strength to help support the brick wall and at thesame time be resilient enough to admit of a slight movement between thebrick shell and the wooden structure which would ensue upon swaying ofthe building under wind pressure.

It is quite possible to apply this device to a Wall already built, bydriving the tongue 17 into the green mortar until the base plate restsflat against the brick and'then setting the studding against said plateand between the flanges in the spacethus adorded. In so driving in thetongue the ears 19 may become inclined somewhat, but that will have nodisadvantageous effect.

` What l claim is l. The herein described bonding strap comprising anupright body` plate having right angular flanges along its upright edgesspaced to receive the studding, said fianges being perforated forfastening devices, the entire plate being U-shaped in cross section, andan integral horizontal tongue projecting at right angles from the upperend of said body plate away from the fianges and roughened, for thepurpose set forth.

2. The herein described bonding strap comprising an upright body platehaving upright perforated flanges along its side edges spaced to receivethe studding whereby the plate is U-shaped in cross section, and anintegral horizontal tongue projecting from one end of said body plateand in a direction opposite from said flanges and adapted to passbetween courses in a wall, said tongue having ears struck from it andbent upward on lines transverse to the tongue, for the purpose setforth.

In testimony whereof I affix my signature in presence of two witnesses.i
